Series PLB 05 valves are pneumatically actuated with two port connections and two switching positions with a nominal orifice size of approx. 0.20". The control is carried out using a 3/2-way or 5/2-way pilot valve provided by the customer. Series PLB 05 has been specially designed for glue. This valve series has been successfully used for glue applications (laminated wood gluing and composite lumber) and in bonding applications, up to 375 psi pressure rating.
Series PLB has a special feature – they are hermetically sealed to the outside by a metal bellows and are also equipped with wear resistant valve seats. Media that hardens when making contact with air would destroy a conventional valve. Series PLB can be mounted as a single valve as well as in a manifold block in order to achieve the necessary glue bead spacings for glue applications.
